Q. I see warning messages like
"Host1 Sent/15 size 1428 ignored (no header so we ignore this message)"
Q. I see warning messages like the following:
"Host1 Sent/15 size 1428 ignored (no header so we ignore this message.
To solve this: use --addheader)".
What can I do to transfer those messages?
R1. Use --addheader option, it will add a header like
"Message-Id: <15@imapsync>" and transfer the message on host2.
Duplicates won't happen in next runs.
R1. Like suggested inline, use --addheader option.
Option --addheader will add an header line like
Message-Id: <15@imapsync>
where 15 is the message UID number on host1.
Then imapsync will transfer the changed message on host2.
Duplicates won't happen on next runs.

Q. Is there a way we can specify an age to sync emails?
If yes, can you please share some examples?
R. Yes, with the --maxage or the --minage option.
E.1 Sync only messages less than 2 days old:
imapsync ... --maxage 2
E.2 Sync only messages more than 2 days old:
imapsync ... --minage 2
E.3 Sync only messages more than 30 days old and less than 365 days old:
imapsync ... --minage 30 --maxage 365
E.4 Sync only messages less than 30 days old or more than 365 days old:
imapsync ... --maxage 30 --minage 365
Full explanation:
--maxage <int> : Skip messages older than <int> days.
final stats (skipped) don't count older messages
see also --minage
--minage <int> : Skip messages newer than <int> days.
final stats (skipped) don't count newer messages

Server specific issues and solutions

Q. From Zimbra to XXX

--exclude "Quick Step Settings" \
--exclude "News Feed"
=======================================================================
Q. From or to HMailServer version 4.4.1.
R. You have to add prefix and separator manually because 4.4.1 doesn't
honor the NAMESPACE imap command.
Example for host1:
imapsync ... \
--prefix1 "" --sep1 .
No specific option for HMailServer 5.3.3 since NAMESPACE is supported.
Maybe --subscribe_all will help you to see all migrated folders.
=======================================================================
Q. Synchronizing from Kerio Connect to XXX
R. No special options required.

Maybe add other --regextrans2 to change folder names and see the result.
When satisfied, run without --dry --justfolders

Q. Synchronizing from Yahoo to XXX
R. Use --host1 imap.mail.yahoo.com --sep1 '/'
./imapsync \
--host1 imap.mail.yahoo.com \

--password1 secret \
--host2 XXX \
--user2 billy \

Can also add --ssl1 to gain encrypted transfer from yahoo.

comments)]) to folder Alexander: 46 NO Invalid folder: Sent (Failure)
In fact folder "Sent" is just the last folder listed previously
as a:

Q. Migrating from or to Parallels Plex Server
R. It depends on the OS

Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail but the tool copies everything in /home/user, how
can i avoid that?
Two solutions:
R. Use
imapsync ... --include '^mail'
R. or (better)
imapsync ... --subscribed --subscribe
=======================================================================
Q. I'm migrating from WU to Cyrus, and the mail folders are under
/home/user/mail directory. When imapsync creates the folders in
the new cyrus imap server, it makes a folder "mail" and below that
folder puts all the mail folders the user have in /home/user/mail,
i would like to have all those folders directly under INBOX.
R. Use
imapsync ... --regextrans2 's/^mail/INBOX/' --dry
look at the simulation and if all transformations seem
good then remove the --dry option.
=======================================================================
Q. Migrating from Groupwise to Cyrus
R. By Jamie Neil:
I eventually managed to get the mail to migrate without errors using the
following options:
--sep1 /
- doesn't report separator so has to be set explicitly.
--nosyncacls
- doesn't support ACLs.
--skipheader '^Content-Type'
- MIME separator IDs seem to change every time a mail is accessed so
this is required to stop duplicates.
--maxage 3650
- some messages just don't seem to want to transfer and produce the
perl errors I mentioned before. This prevents the errors, but the
bad messages don't transfer.
Even though the mail migrated OK, there are a couple of gotchas with
Groupwise IMAP:
1) Some of the GW folders are not real folders and are not available
to IMAP, the main problem one being "Sent Items". I could find no way
of coping the contents of these folders. The nearest I got was to
create a "real" folder and copy/move the sent items into it, but
imapsync still didn't see the messages (I think because there is
something funny about the reported dates/sizes).
It think this problem has been rectified in GW6.5.
2) The "skipheader '^Content-Type'" directive is required to stop
duplicate messages being created. GW seems to generate this field on
the fly for messages that have MIME separators and so it's different
every time.
3) Version 6.0.1 of the Groupwise Internet Connector sucks. I was
getting server aborts when I pushed it a bit hard! I eventually had to
upgrade to 6.0.4 which seems to be a lot more stable.

Q. I need to migrate 1250 mailboxes, passwords are in a MySQL Database.
Can you tell me if your script suits my needs?
R. Mailboxes must exist before running imapsync.
You have to extract users logins and passwords in a csv file.

Q. From or to QQMail IMAP4Server
R. imapsync ... --noabletosearch

Q. From FirstClass to XXX
http://www.firstclass.com/
R. Migrating from FirstClass is not easy because FirstClass, strangely,
does not show all messages via IMAP. To make it show all messages,
a trick, painful to follow by hand, is moving emails
out and back in, for each folder. May be it can be done by a script.
FirstClass releases prior to release 12 do not shows the "Sent"
folder in IMAP but FirstClass release 12 shows it.
I advice you to upgrade to FirstClass release 12 before leaving it
with imapsync or another imap tool.
Here is a command line used to migrate from FirtClass release 12:
imapsync ... \
--tmpdir /var/tmp --usecache \
--useheader Message-ID \
--idatefromheader \
--addheader \
--regextrans2 "s,(/|^) +,\$1,g" --regextrans2 "s, +(/|$),\$1,g" \
--regextrans2 "s/[\^]/_/g" \
--regextrans2 "s/['\"\\\\]/_/g" \
--regextrans2 "s,&AC8-,-,g" \
--regextrans2 "s,&APg-,oe,g"
On Windows, in the previous example containing \$1 you have to
replace the two \$1 by $1 (remove the \ before $).
Special thanks to Kristian Wind and Joey Alexander for helping me
writing this FAQ item.

Q. From XXX to FTGate
R. Do NOT use --usecache since new UIDs are not given by FTGate and also
badly guessed by imapsync. UIDEXPUNGE does not work so use also
--expunge2 when using --delete2
